Changing administrator password in Oracle 9i

1. Open the DOS command prompt and enter: sqlplus /nolog
2. Type : connect / as sysdba
3. Type : alter user sys identified by new_password;

This alters the password for the adminstrator (sys).

Oracle 9i and WSAD 5.1.2

Installed the Oracle 9i database and client on my PC. Select * from emp; query shows all the records in the emp table from the SQL window. So, the installation issuccessful. Some of the components are mutually exclusive and during the installation it does let the user know about this.

WSAD 5.1.2 installation messed up my existing Eclipse 3.0 installation. I cannot bring up the Eclipse anymore. Is this due to the WSAD 5.1.2 using Eclipe 2.1 ? My plan is to install Eclipse on the laptop when I get one.

Changed the Oracle db related services to run manually instead of automatic. TNS listener and the DBName processes must be started to use the database. Need to download the JDBC driver classes12.zip. I think it is free. Once the database is setup, I can start playing with Hibernate framework.

Balanced Programming

After reading all the hype about Xtreme programming by the Software Swamis, I would like to introduce the Programming Community to my theory of Balanced Programming. This concept is similar to the idea of Balance as the key to leading a good life. Balanced Programming recognizes the good aspects of other programming theories and balances them to a level that optimizes the benefit of software productivity and quality. Think of it as a stereo tuning with several different controls to optimize the frequency of the particular type of music that you are hearing.

In this theory, neither the design is considered dead nor is programmer testing detested. Design is done when necessary to improve the quality of the code base without getting stuck in analysis paralysis. Testing is also done when it gives most value and is one of the primary means of finding Interfaces.

Nice tool to generate :

toString()
hashcode()
equals(Object)
compareTo(Object)

from Eclipse.

Estimating taxes for the self employed

This site looks interesting. I will post later if the estimates were good after consultation with a tax professional.
